Pros:

• Good build quality for the price.
• USM. Quick and silent focussing.
• Light and Compact
• Optically good.
• 24mm is a very useful focal length on a digital body.

Cons:

• Questionable quality control. Empirical evidence shows a fair chance of buying a lemon. Be sure to buy it from somewhere with a good return policy.
• A little pricey compared with the Canon EF 28-105mm USM II

Additional Comments:
A very nice beginner lens. No complaints about the image quality, mechanically sound, availability of USM, compact size and a useful focal length all sum up to an excellent all purpose lens. There is some murmuring about getting bad samples of this lens but all the ones that I have handled seemed fine. Many stores have forgiving return policies so don't be afraid to try it.
